Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042120, here are decompositions:

11 + 1042109 = 1042120
17 + 1042103 = 1042120
29 + 1042091 = 1042120
137 + 1041983 = 1042120
227 + 1041893 = 1042120
251 + 1041869 = 1042120
257 + 1041863 = 1042120
263 + 1041857 = 1042120

Showing the first eight; more decompositions exist.
